UNITED STATES OKE S. WIBEBG, OF CHICAGO, ILLINOIS.

WINDOW FOR LOCOMOTIVE CABS.

Application filed November 12', 1924. Serial No. 749,434.

To all whom it may concern:

Be it known that I, OKE S. WIBERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Vindows for Locomotive Cabs, of which the following is a specification.

This invention relates, generally, to improvements in windows, but particularly to windows for locomotive cabs, and has for its principal object the provision of an adjustable or swingingly mounted sash or frame withinv a frame, of such construction and arrangement of its parts that glass lights or panes therefor can be easily rc. moved therefrom and readily and quickly inserted therein, as well as, that when a glass light or, pane shall have been inserted in the said sash, it will be securely and safely held in place against accidental dislocation.

Another object is to furnish an adjustable or swingingly mounted sash or frame having the above mentioned characteristics, which is especially adapted, but not restricted thereto, for use in connection with a main or window frame located in a door which permits passage from a locomotive,

cab to a running board at the side of the engine which main or window frames areeach usually equipped with upper and lower lights or panes of glass separated from each other at their adjacent edges, in which space thus afforded, my improved window is located and operates. j

A further object of the invention is, to furnish a window of the above mentioned kind, in which clear or unobstructed vision will be afforded the engineer, when the ad- 'justably or swingingly mounted member thereof occupies either a closed or open position.

Still another'object is to so construct parts of the adjustably mounted frame that when in its lowered or closed position interference with the removal of the lower pane of the main frame, should the same require it, on account of being broken or otherwise, will be avoided.

Other objects and advantages of the in- I vention will be disclosed in' the following description and explanation.

The'invention consists in certain peculiarities of the construction, novel arrangement and combination of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

In the accompanying drawing,

Fig. l is a front face view of a portion of a window embodying my invention showing parts thereof shortened for the convenience of illustration. 7

Fig. 2 is a vertical sectional view taken on line 2-2 of Fi 1 looking in the direction indicated by t e arrows.

Fig. 3 is a similar view of a part of the main frame of the window illustrating different positions to which the adjustably mounted sash or frame thereof may be positioned, and

Fig. 4: is a greatly enlarged plan sectional view of one side .of the window taken on lineal-4 of Fig. 2.

Corresponding numerals of reference refer to like parts throughout the different views of the drawing.

The reference numeral 5 designates a vertically elongated rectangular frame which may be made of wood or other suitable material and may be employed as a door to permit egress from a locomotive cab to a running board on one side of the engine, or it may be used as a stationary window frame in the front of said cab. This frame 5 has fitted in its upper portion a pane of glass 6 which rests at its lower edge on the upper surface of the top or horizontally disposed rail 7 of a rectangular main frame 8 which is closely fitted in theframe 5, and as is clearly shown in Fig]. 1 of the drawing, is of a three-sided rectangular form, that is, the lower horizontal rail or member thereof is omitted, but each of the side rails 9 thereof has at its lower end a horizontal extension 10, which extensions. lie in the same plane and project towards each other, as

.shown. The pane of glass 6 may be secured in place by means 0 cleats 11 secured by means of screws 12 to the frame 5 so as to rest on the outer surface of said pane at its side and upper edges.

The top or horizontal rail 7. of the main frame '8 has at its inner portion a downshown in Fig. 1 is in the form of a three sided rectangular figure, that is, has its lower horizontal rail omitted. The upper or horizontal rail 16 of the frame or sash 15 is secured by means of pivots 17 to the upright sides of the frame 8 just below the horizontal or top rail 7 of the frame 8 and outwardly of the flange. 13 which depends from the rail 7, and said rail 16 is provided with a longitudinal slot or guide-way 18 for the reception of a pane of glass 19 with which the frame or sash 15 is equipped. Each of the side rails 20 of the frame 15 is provided on its inner surface with agroove or chan nel 21 to receive and detachably hold the side edges of the pane 19, it being understood that the said grooves 21 terminate at their lower ends or the ends thereof opposite the pivots of the frame 15 short of the side rails 20, thus affording closed ends to support the lower edge of the pane 19 of the swinging frame of the device.

Each of the side rails 20 of the frame 15 is provided in its lower portion with a recess 22 the vertical wall of each ,of which is downwardly and forwardl 'inclined, see Figs. 2 and 3, and correspon in shape and size with recesses 23 formed in the lower portion of the side rails 9 of the frame 8, 'see Fig. 3 of the drawings. By this arrangement it is apparent that when the frame 15 is in'its lowered osition as shown in Fig. 2 of the drawing, t e pane of glass 14 can be removed, if required, without interference by the frame .15, by simply removing the cleats 11 which hold said pane in position, as the beveled or inclined portions'of the recesses 22 and 23 of the frame 15 and 8 respectively will permit the pane 14 to be.

, curved slot 27 in an arm 28pivoted at one of its ends to a lug 29 on one of the side rails 20 of the frame 15, in such a way as to adjustably support said frame in various positions with respect to the main frame 8 and frame 5, and also in such a way'as to firmly secure the frame 15 in its lowered or. elesired to remove a, pane of glass 19 from the frame 15 as such a screw 26 must be removed from its socket or bracket to permit the frame 15 to be positioned as shown by dotted lines in Fig. 3, when it is evident the slot or guide-way 18 in the top rail of the frame or sash or any horizontally disposed rail at the upper edge of the pane 14 to obstruct his vlslon. It is also apparent that when the frame or sash 15 occupies its lowered position, the pane 19 thereof will overlap the upper part of the pane 14 and thus to a large extent prevent the admission of cinders, rain, snow and dust and the like between the adjacent edges of said panes, as they will be directed downwardl When in its closed .position the adjustable frame or sash 15 can be securely held in such position b tightening the thumb screw 26 so as to ho d' the arm 28 in about the position shown in Fig. 2 of the drawing. It is also dotted lines in Fig. 3 anda clean or unbroken glass can be immediately inserted in said frame or sash.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination in a locomotive cab and window therefor, of a sash mounted at its top in the frame of the window, said sash being open at its bottom and havin a top horizontal and slotted rail pivota y 'mounted in said frame'and provided on the inner surface of each of its sideswith a groove in communication at one of its ends with said slot, each groove having its lower end closed, a glass pane removably locatedin said grooves and slot, and stopping means on said frame arranged to prevent the removal of said glass pane until the sash shall have been turned on its pivots to a predetermined point.-

2. In a window of the class described, the combination with an upright frame such as that of a door or window having a glass pane inits lower portion, of a bottomless angular frame fi'xed in the first named frame with its "lower portion adjacent the upper art of said ane'and having at its tog a orizontally isposed rail provlded wit a depending part at its rear edge, a sash open at the bottom and having a top horizontal 5. and slotted rail pivotally mounted in said o fixed frame below the said top or horizontal rail thereof and in front of its said dependmgpart, a glass pane removably located in sald-slot, sa1d depending part arranged to prevent the removal of said pane'until the sash shall have been turned on its pivots to a predetermined point, a slotted supporting arm pivotall secured at one of its ends to said'sash, an a screw extended through said 15 slot and detachably enga g a fixed part.

3. The combination wit a fixed rectanguinner surface 0 hr frame having at the rear part of its bop rail a depending portion, of a rectangular sash open at its bottom and having a top horizontal and slotted rail pivotally mount- 20 I on its pivots to a predetermined point.
